Product Description
Bridge Rubber Bearings Overview
Rubber bearings, also known as elastomeric bearings, are essential components in modern bridge engineering. Positioned between the bridge superstructure (deck and beams) and substructure (piers and abutments), they provide controlled movement and structural flexibility.
Key Functions & Applications
Primary Functions
- Accommodate thermal expansion and contraction
- Support vertical loads up to 1,936 kN
- Provide structural flexibility and movement control
Application Scope
Suitable for bridges with spans less than 30 meters and minimal displacement requirements. Available in round board and rectangular plate configurations for different bridge types and pier designs.

Maintenance Guidelines
Regular inspection should ensure all bearing components remain intact and clean. Remove debris, snow, and ice from surrounding areas, clean sewage and grease, and promptly drain water from piers and caps to maintain optimal performance.
Load Capacity Factors
Bearing capacity depends on three critical scenarios: rubber crushing or shearing, excessive compression/shear deformation beyond allowable limits, and separation failure between rubber and support interfaces.
